Title: Method for treating surface of silicon substrate after dry-etching process
Inventor: ZE SUN ZON
IPC: H01L21/3065
Filed: 1993-11-22
Abstract: PURPOSE: To recover surface profile to the degree of surface profile of the initial bare silicon wafer by etching exposed surface of a silicon wafer with Electron Cycrlotron Resonance(ECR) after dry etching process. CONSTITUTION: The region damaged from the plasma is removed by thin etching a surface of a silicon wafer by ECR etching after main etching process. In ECR system, a plasma is induced by microwave, magnetic field is produced in the plasma in a chamber by providing magnets around the chamber in the manufacturing process, and particles such as electrons cause the plasma to resonant, so that there is not any damage to the surface because ion density is higher than other systems and ion energy is lower than other ones. The surface of the silicon wafer is thin etched with ECR system using gas, for example, suitably combined SF6 gas with O2 gas.

IPC: H03L7/183
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To provide an external reference input frequency automatic changeover circuit that can automatically switch a reference input frequency in spite of a simple circuit configuration. SOLUTION: A lock detection circuit 7 detects a lock state of a PLL. When the lock detection circuit 7 detects an unlocked state, a pulse generating circuit 8 generates a pulse to a frequency division ratio setting circuit 9 at a prescribed time interval until the PLL is locked. When the frequency division ratio setting circuit 9 receives the pulse from the pulse generating circuit 8, the frequency division ratio setting circuit 9 gives a setting signal S8, to select a value in matching with an external reference signal S0 inputted from a terminal 10 for a frequency division ratio of a frequency divider 2 receiving the reference signal of the PLL, to the frequency divider 2.  When the frequency division ratio of the frequency divider 2 is set to a value in matching with the reference signal S9 and the PLL is locked, the production of the pulse from the pulse generating circuit 8 is stopped.

Title: Video tape recorder
Inventor: HIRASAKA HISAKADO
IPC: H04N5/91
Filed: 1991-11-28
Abstract: PURPOSE:To recognize the recording state of a 1st signal while 1st and 2nd signals are being recorded by recording the 1st signal onto a deep layer track and reproducing the signal before the 2nd signal is overlappingly recorded on the track. CONSTITUTION:An audio signal recording magnetic head 6, a video signal reproducing magnetic head 15, an audio signal recording head 7 and a video signal magnetic head 14 are arranged along the head of a rotary drum 19 in the rotating direction in this order, and the head 15 is located in the vertical direction of the drum 19 uper by one track width of the magnetic tape 1 than the heads 6, 7, 14. Thus, the head 6 records a signal onto a deep layer track. Thus, an FM audio signal is reproduced by the head 7 just after the FM audio signal is recorded by the head 6. Since no overlap recording is implemented to the deep layer track by the head 14 in this case, the reproduction level of the audio signal is high, the S/N is improved and the FM audio signal is reproduced even in the presence of noise due to crosstalk of the recording signal.

Title: Memory access circuit
Inventor: HIDAKA TAKAHARU
IPC: G06F13/16
Filed: 1986-12-24
Abstract: PURPOSE:To inexpensively obtain a stable memory data signal with a simple constitution by closing the data gate of a memory, which is accessed with a memory address signal, at the glitch occurrence timing. CONSTITUTION:Normally, a memory 1 has an unstable address accessed at the rise and the fall of a memory address signal 4 at the time of switching the memory address signal 4, and glitch occurs on a memory data signal 9. This glitch occurs at the fixed timing after switching of the memory address signal 4 of the memory 1. Since the memory address signal 4 is generated synchronously with a clock signal 8, a gate control signal 10 is generated from the clock signal 8 at the glitch occurrence timing by a gate control circuit 11 having a delay circuit 12. The data bus gate in the memory 1 is closed by this gate control signal 10 only for the time of glitch occurrence, namely, for a set time after address switching. Thus, glitch is not driven onto a data bus and the data level is held.

Title: Space charge measurement method
Inventor: ADACHI MIKIO
IPC: G01R31/08
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To accurately measure space charge in the insulator layer of a power cable, without removing the sheath and shielding layer of the power cable. SOLUTION: After a DC voltage is applied between a conductor 51 and a shielding layer 55 of a power cable 50 and a surface charge is induced, a pulse voltage is applied between the conductor and the shielding layer, and a pressure pulse based on the surface charge is generated in the conductor and the shielding layer. A displacement current that flows in response to a space charge in the insulator layer being moved sharply by the pressure pulse is measured to obtain the space charge. Also, a pulse current is fed between the conductor and the shielding layer of the power cable, and the pressure pulse due to pinching effect being generated at the conductor and the shielding layer may be generated at the conductor and the shielding layer.  Further, an external magnetic field is applied to the power cable, and a pulse current is allowed to flow between the conductor and the shielding layer, so the pressure pulse based on the external magnetic field may be generated at the conductor and the shielding layer.
